Why to use ENERGY STAR Qualified Compact Fluorescent Lights (CFLs):

  • Last up to 10 times longer than standard incandescent bulbs
  • Use 1/3 the energy of ordinary bulbs
  • Save an average of $30 each or more in energy costs over their lifetime; change five bulbs to ENERGY STAR and save more than $150!
  • Fit in almost any fixture, for indoors and outdoors
  • Convenient in hard-to-reach and high-use fixtures because of their long life
  • Generate 70 percent less heat than standard lighting, cutting home cooling costs
  • Provide the same amount of light (lumens) as standard incandescent bulbs, but use fewer watts of energy Backed by a minimum 2-year manufacturer warranty
  • Prevent more than 450 pounds of greenhouse gas emissions each over their life

Where to use:

  • To get the most energy savings, replace bulbs where lights are on the most, such as your family and living room, kitchen, dining room, and porch
  • Remember, CFLs work better in open fixtures that allow air flow

How to choose:

  • Matching the right type of CFL to the right kind of fixture helps ensure that it will perform properly and last a long time. Read the packaging to be sure that the type you choose works for the fixture you have in mind. For example:
  • For recessed fixtures, it is better to use a ‘reflector’ CFL instead of a standard type
  • If a light fixture is connected to a dimmer or three-way switch, select CFLs that are labeled as appropriate for a dimmer or three-way switch
  • To get the right amount of light, choose an ENERGY STAR qualified light bulb that offers the same light output, or lumen rating, as the light you are replacing. The higher the lumen rating, the greater the light output
  • Choose the color that works best for you. For example, while most CFLs are created with warm colors for most rooms in your home, you might choose a cooler color for task lighting

What to do when a CFL Burns Out:

EPA recommends that consumers take advantage of available local recycling options for compact fluorescent light bulbs. EPA is working with CFL manufacturers and major U.S. retailers to expand recycling and disposal options. Consumers can contact their local municipal solid waste agency directly, or go to www.epa.gov/bulbrecycling or www.earth911.org to identify local recycling options. If your state permits you to put used or broken CFLs in the garbage, seal the bulb in two plastic bags and put it into the outside trash, or other protected outside location, for the next normal trash collection. CFLs should not be disposed of in an incinerator. ENERGY STAR qualified CFLs have a warranty. If the bulb has failed within the warranty period, look at the CFL base to find the manufacturer’s name. Visit the manufacturer’s web site to find the customer service contact information to inquire about a refund or replacement.
